OBJECTIVE To describe the histopathological pattern of skin diseases in patients from the western region of Saudi Arabia and to compare this with previously published data from other regions in Saudi Arabia and worldwide. METHODS A retrospective review of all skin biopsies received and reported by the Department of Pathology, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabi...

We present a case of a clonal nevus arising from a previously banal melanocytic nevus over a 15-month period on the central back of a 30-year-old woman in a primary care skin cancer practice in Melbourne, Australia. Clinical, dermatoscopic and dermatopathologic images are presented. A search of the literature has discovered no previously published dermatoscopy images of an evolving clonal nevus.

Melanoma is one of the most lethal skin neoplasms among dogs and cats, and its incidence is increasing worldwide in the last years. The relation between the study of tumor biology and epidemiologic data from melanocytic tumors (melanomas and melanocytomas) can help in the achievement of an earlier and safer clinical diagnosis. However, epidemiologic data for these neoplasms are still rare in Br...

A part of collection of new algorithms for synthesis of melanocytic skin lesion images is briefly described. Presented approach in the developed algorithms based on a semantic conversion of textual description of melanocytic skin lesions into hybrid (vector-raster type) digital respective images of such lesions. It is assumed, that the developed methodology could be successfully used in educati...

The concern about malignant skin neoplasms leads to the excision of smaller lesions. This study on small melanocytic lesions aims to evaluate the range of possible histopathological diagnoses, describe histopathological aspects, and assess the usefulness of serial histological sections. We performed a cross-sectional descriptive histopathological study examining 76 pigmented skin lesions up to ...

There is concern that growth hormone (GH) therapy may influence the growth of melanocytic nevi. In a review of the experience of the National Cooperative Growth Study, we found no excess of skin cancer in children who were treated with GH. We also reviewed our experience in 90 children with GH deficiency and 24 with Turner syndrome. We found no difference in the nevi count between control subje...

Garment-like giant congenital melanocytic nevi are very rare, and those being treated are most often offered excision and split-thickness skin transplantation. Due to the risk of restricted mobility secondary to shrinkage and hypertrophic scarring of the transplant, we treated to date the largest reported giant congenital melanocytic nevus (16% total body surface area) with Integra dermal regen...
